NORTHAMPTON _ Whiskey drinking donkeys, microphone stands with cup holders, and smiling Irish eyes all-around were the key ingredients of Gaelic Storm’s “Shamboozle” tour which fell into the laps of a thousand fans at the Calvin Theater on Saturday night.

Almost a full week removed from the last of the local St. Patrick’s Day celebrations, Gaelic Storm declared the holiday extended with a two-set, two-plus hour, 19-song party that featured songs off their latest release “Cabbage,” along with much of their popular past catalog.

For the uninitiated, Gaelic Storm is part of the Holy Trinity of Celtic rock bands that have claimed Northampton as a second home. Like the Saw Doctors and Enter the Haggis, Gaelic Storm has earned a legion of local fans that know every word to every song and fill the concert halls of the Valley whenever they show up on the marquee.

Led by the affable Patrick Murphy and the equally personable Steve Twigger, the band boasts hand drums (Ryan Lacey), bagpipes (Peter Purvis), and the fiery fiddle of Jessie Burns.

It was the latter two that led off the show, facing off against each other while Murphy and Twigger backed them with accordion and acoustic guitar. The reel eventually led to “The Beggarman,” and the festivities were underway.

The group has an amazingly unfettered and organic sound, filling the spaces with tin whistles, bodhran, mandolin, and even spoons. Even without the bombast of electrified instrumentation, the band brings it and its audience responds.

The audience was chided a bit by Murphy for not being raucous enough, comparing the group unfavorably to the previous night’s crowd in Albany. The accusations were unfounded, but served as a running gag throughout the night.

The crowd was intimately involved and engaged, taking sides on “Me and the Moon,” and singing along with classics “Johnny Tarr,” and “Johnny Jump Up.” Murphy also had the audience rapt with his blow-by-blow description of an actual bar fight with actor Russell Crowe as a prelude to the aptly-titled song “The Night I Punched Russell Crowe in the Head.”

The band didn’t employ an opening act but did break for a 20 minute intermission to allow for the selling of merchandise and refreshments and as Murphy pointed out “one hundred percent of the proceeds from the sale of these t-shirts go directly to ….Gaelic Storm.”

It was the grandeur of the Highland pipes that opened the second set and one fan’s half-hearted attempt at dancing during “Darcy’s Donkey” opened the door for Murphy to harass the crowd again.

The group delivered Simon and Garfunkel’s “Cecilia” with a musical brogue had the audience standing for “Slim Jim and the Seven Eleven Girl.”

Twenty fans were invited on stage to share in the encore (40 made it up) as the band sang “Kiss Me I’m Irish,” “What’s the Rumpus,” and “Tell Me Ma.”
